Rigid Flat Punch on Flat: Online Calculator
Indentation by a Rigid Flat Punch
This calculator allows calculating pressure , displacement (elastic deformation)
, stiffness
, average pressure
and resultant force
for the case of indentation of an elastic half-space by a rigid cylindrical flat indenter. In this case, the intender is rigid and of cylindrical shape. The substrate is elastic, the geometric parameters
– rigid body displacement,
– radius of the cylinder and material parameters
are the inputs (see the figure and definitions below). The stress distribution in the contact area and the displacements of the half-space outside the contact are:
(1)
where is the maximum displacement due to the deformation,
is the radius of the punch and
is the radial coordinate.
The contact stiffness can be calculated as follows:

Equations were taken from [1].
Definitions:
Poisson’s ratio dimensionless,
Young’s modulus of elasticity , [Pa],
Equivalent elastic constant , [Pa],
Normal load , [N]
